If you plan on running the laptop all the time on wall power, make sure to limit the battery charge to 80 % or less, otherwise the battery will die pretty quickly.

Yes, using uuidgen should work fine.

Thanks for pointing this out. I thought this had to be an actual UUID. Generating a unique string of arbitrary format manually is certainly much easier to do manually without additional tools.

This is not quite true. As I mentioned in my other comment already, each feed entry needs its own unique UUID. You have to generate such a UUID for every entry.

How do people subscribe to them?

Subscribing to an RSS feed really is nothing more than telling your RSS client about the URL to that RSS XML file. The RSS client then regularily checks the URL for changes.

If your site is hand-made as you say, you would have to manually create and update the RSS file also. This is quite a nuisance, not only because it is XML, but also because every feed entry needs its own unique UUID, which you need to create. Perhaps you could create a script that does it for you. Static site generators are usually able to automatically create an RSS feed for you.

Correct, you summarized that well.

The easiest way to do it is by running a Kiwix server and hosting a copy of Wikipedia with that.

I am not sure which CPUs exactly the article is refering to with those early i586 CPUs, but I do remember those Cyrix 6x86/6x86MX CPUs. When it comes to Linux, they were always treated as 486-class CPUs because they were missing some instructions required to be considered 586-class. On the other hand their architecture was actually quite modern, like a 686 CPU with out-of-order execution. The 6x86MX also supported the CMOV instruction which is usually associated with 686-class CPU. Quite strange CPUs from today’s perspective.

VIA also had some CPUs (certain VIA C3 CPUs) that the Linux kernel always treated as 486-class CPUs due to some missing 586 instructions.

AMD’s Am5x86 CPUs were rebranded 486 CPUs, while AMD’s K5 was an early 586 CPU that might fall into that early 586 category due to missing instructions. AMD’s later K6 CPUs should support all Pentium instructions afaik (but not CMOV like the Cyrix CPUs did).

I’ve subscribed to their RSS feed, but their server is so unreliable, my feed reader complains all the time that it is unreachable. When I manually retry it mostly works, only to fail again later. I’m wondering what’s going on there. I never have this problem with any other feed…

Oops, you are correct of course, 6A is what I meant, plain 6 should work fine also most of the time, but there is pretty much no point going for that, unless you have that deployed already.

Can anyone explain to me if a headless chrome browser is dangerous the way a regular chrome browser is?

Almost. You want to make sure to keep it as up-to-date as you would a regular Chrome browser. It does almost everything a regular Chrome does, including running arbitrary scripts on websites.

Anyone have experience converting from 1G LAN to 2.5 or even 10?

Going from 1 G to 2.5 G is fairly cheap these days. You can almost certainly use the same cabling, even when you’ve got only Cat.5e cabling. While you can do 10 G over copper, I wouldn’t suggest doing that, since it consumes quite a lot of power compared to both 1 G and 2.5 G. You’d need Cat.6E for reliable 10 G over copper.

I don’t know your exact setup, but you should add the IP that Jellyfin sees when the reverse proxy makes a request. That probably comes from the IP of your Traefik docker container.

Thanks for pointing this out! I probably would have missed this, since I didn’t expect such a change for a patch release.

Their documentation mentions:

For jellyfin to know which reverse proxy is trusted, the IP, Hostname or Subnet has to be set in the Known Proxies (under Admin Dashboard -> Networking) setting.

Does this really mean, that the only way to configure this is through the web UI? This is kind of a problem when deploying it, since without the reverse proxy I can’t reach the Jellyfin server. Is there no way of doing this outside the web UI, via a config file or something?

Edit: Apparently the configuration for the proxies is stored in Jellyfin’s network.xml config file. So it should be possible to do this without manually configuring it via the web UI.

Another edit: It works. Adding <KnownProxies>[proxy ip or hostname]</KnownProxies> in place of the empty <KnownProxies/> key to that config file does the trick.

It’s on April 1st, but nobody takes it seriously.

72 hours isn’t a lot. Many countries strongly suggest having emergency supplies for at least 10 to 14 days.

I like Miniflux.

The at load efficency isn’t always the most important metric, depending on what you are using the machines for. If they are mostly idle, efficiency isn’t too bad. Many server tasks don’t load the CPU to the fullest anyway.

They are not too terrible really. 3rd gen i7 is the Ivy Bridge generation, so 22 nm. For many homelab server tasks the CPUs would be just fine. Power efficiency is of course worse than modern CPUs, but way better than the previous 32 nm Sandybridge generation. I had such a system with integrated graphics and one SSD and that drew 15 W at idle at the wall.

Pi Zero uses the CPU from the 3

No, the original Pi Zero uses the CPU of the Pi1 (only clocked higher). So it is quite a bit slower than a Pi 2, since it has only a single ARMv6 CPU core. Still fine for a DNS server on a typical home network.
